Abstract: PURPOSE: To enhance the adhesion strength of a cover by forming a yoke by laminating thin sheets formed to the same projected shape of a yoke plane, providing a linkage notch near an open end of an arbitrary thin sheet constituting an intermediate laminated portion of the yoke, and by forming a cover and a linkage to the linkage notch and an outer surface of the yoke. CONSTITUTION: Thin sheets 11 lacking in linkage notches 15 are prepared. Then, by sequentially laminating the shin sheets, a yoke 1 having linkage notches can be formed. After giving electroless Ni plating treatment to the outer surface of the yoke 1 formed by lamination, a spacer 14 is fixed to a recessed portion 14a with an adhesive, and a cover 20 is applied by injection molding with an insert nut inserted to a hole 10a for insert nut. At the time of forming of the cover 20, a liquid crystal polymer is also injected to the linkage notch 15 and a through hole 16 thereby forming a linkage as one united body with the cover 20, by which the adhesion strength of the cover 20 near the open end of the yoke 1 can be improved and peeling-off of the cover 20 can be prevented.

Title: Switching element driving circuit
Inventor: KAMEDA YUKIHIRO
IPC: H03K17/00
Filed: 1994-09-09
Abstract: PURPOSE: To extend an input voltage range by a simple constitution by providing a driver circuit of low withstand voltage which is turned on/off by turning on/off a control circuit and driving a switching element by this driver circuit. CONSTITUTION: When a transistor(TR) Q01 for driving is turned on, the voltage divided by resistors R03 and R04 is applied between the base and emitter of a driver transistor Q03, the TR Q03 is turned on and a switching transistor Q02 is turned on. When the Q01 is turned off, the emitter voltage of the TR Q03 is raised up to the voltage resulting from adding the voltage drop amt. of a diode D02 to a power supply voltage Vc for control circuit at the same time when the TR Q01 is turned off. Because only the voltage resulting from dividing the voltage drop amt. of the diode D02 by the resistors R03 and R04 is applied between the base and the emitter of the TR Q03 in this state, the TR Q03 is turned off and also the Q02 is turned off. Thus, high input voltage can be controlled by a control circuit of low withstand voltage.

Abstract: PURPOSE:To make image quality higher by deciding the rubbing force generated when a magnetic brush rubs on a photoreceptor by a minute rotational load detecting sensor and adjusting a distance between a drum and a developing roller. CONSTITUTION:In the case of measuring the rubbing force obtained when the magnetic brush rubs on the photoreceptor, the driving gear of the photoreceptor drum 42 gets out of a solenoid clutch, and a fixed pulse wave is detected from an encoder 45 attached to a drum shaft and inputted in a CPU 40 through an amplifier 46. The CPU 40 compares the measured result with the value of optimum rubbing force at the time of obtaining high image quality. When a difference is found between the values, a signal is transmitted to a DSD collar deciding a distance between the drum 42 and a developing roller 41, and the collar is rotated by the angle of several degrees by a stepping motor 51 so as to obtain the optimum distance between the drum 42 and the roller 41. Then, a flange on the drum 42 side coming in contact with the collar is formed like a bearing and controlled to obtain the optimum distance between one drum 42 and the roller 41.
